Attitude controlling system for vehicle-supported equipment
First Claim
1. An attitude controlling system for vehicle-supported equipment comprising:
- a vehicle-supported attitude controlling mechanism for setting an attitude of at least one vehicle-supported equipment such as a steering wheel or seat;
an electric drive source for driving said vehicle-supported attitude controlling mechanism;
attitude detection means for detecting the attitude of said vehicle-supported equipment;
at least two vehicle stoppage detection means for outputting signals in response to the presence or absence of stopping of a vehicle and the boarding/alighting action of a driver; and
electronic control means for controlling an automatic operation for energizing said electric drive source to automatically set said vehicle-supported equipment into a boarding/alighting position when said vehicle stoppage detection means outputs at least two signals indicative of stopping of the vehicle and alighting action of the driver and for energizing said electric drive source to automatically set said vehicle-supported equipment into a driving position when said vehicle stoppage detection means outputs signals indicative of release from stopping of the vehicle and boarding action of the driver and for controlling a manual operation energizing said electric drive source in accordance with a state of said manual attitude adjusting switch for inhibiting said automatic operation when said mode changing switch is turned off and for inhibiting said manual operation when said engine stoppage detecting means detects engine stoppage, and wherein said electronic control means monitors the voltage of a vehicle-supported battery and, when the battery voltage is lowered less than a predetermined value, inhibits energization of said electric drive source at least during stop of the engine.

Abstract
A tilt steering mechanism, a telescopic steering mechanism and a seat attitude adjusting mechanism are controlled in their attitudes by an electric motor such that the respective attitudes are automatically set into a retreat attitude where the driver easily gets on and off a vehicle upon boarding/alighting, and into a driving attitude assumed before retreat upon the completion of boarding. Whether or not the driver is about to get on and off the vehicle is judged in accordance with the status of an ignition switch, status of a door switch, vehicle speed, status of a parking brake, shift lever position of a transmission, etc. A change speed of attitude is monitored during energization of the electric motor and, if the change speed is less than a predetermined value, this is judged as the presence of overload and the electric motor is stopped.

9. An attitude controlling system for vehicle-supported equipment comprising:
-
a vehicle-supported attitude controlling mechanism for setting an attitude of at least one vehicle-supported equipment such as a steering wheel, seat and others; an electric drive source for driving said vehicle-supported attitude controlling mechanism; attitude detection means for detecting at least one of an attitude of said steering wheel and and attitude of said seat; a manual attitude adjusting switch; engine stoppage detecting means; at least two vehicle stoppage detection means for outputting signals in response to the presence or absence of stopping of a vehicle, or boarding/alighting action of a driver; and electronic control means for controlling an automatic operation for energizing said electric drive source to automatically set said vehicle-supported equipment into a boarding/alighting position, when said vehicle stoppage detection means outputs at least two signals indicative of stopping of energizing said electric drive source to automatically set said vehicle-supported equipment into a driving position, when said vehicle stoppage detection means outputs signals indicative of release from stopping of the vehicle or boarding action of the driver, for controlling a manual operation energizing said electric drive source in accordance with a state of said manual attitude adjusting switch, for inhibiting said automatic operation when said engine stoppage detecting means detects engine stoppage, for monitoring the voltage of a vehicle-supported battery, and for inhibiting said automatic operation and said manual operation when the voltage is lowered less than a predetermined value.
